Hi all.

Just a quick question about tires and rims for my 1993 Impreza AT AWD. Currently I have 14 inch rims with P175 70 14 winter tires on them. My mechanic happens to have a set of rims/tires from a Legacy Turbo (look like the ones that came stock with the 92-94 Turbos) that are in fantastic shape and he will sell to me very cheap. They are 15 inch rims with P195 60 15 Pirelli all season tires.

My question: can I safely (come summer) switch my rims/tires to the 15 inch ones mentioned above? If there will be problems can they be solved easily? Past experiences etc...

Thanks for your help in advance!

They'll be fine. They're rarer wheels so don't go trashing them, but they'll fit.

I've heard that putting larger wheels on a car can affect the speedo amongst other things. Will it affect it with a 1" jump up or is that only if I was going to try and rock 18's or something?

Larger wheels don't make a difference, it's the overall diameter of the tire.

Generally, for every +1" in wheel diameter, you're going to want to go down 10% on the section, and one size wider.

So, like, a 195/60-15 would have about the same diameter as a 185/75-14.

Those 15s are going to be very, very close to the same height as your stock wheels. miata.net has a tire calculator that will tell you how close.

I have 205/55-16s in place of 185/70-14s, and my speedo is still pretty accurate. I checked with GPS and it was off by about 2 mph at 60, which is normal for any car.
